Do encoders count as sensors? I mean those that are used for counting the number of rotation of a motor. There are also torque-meters, tachometers, pressure sensors, etc. In some situations they can even use a variable capacitor or a rheosta for those purposes.

I haven't tried but you may want to assume y = a*cos(t)+b*sin(t)+c*sin(200t)+d*cos(200t) or something like that.

Ahh, teachers :) Okay, search for what "rank" means if you already don't know, then relate the number of linearly independent vectors in S to the rank of S (smaller, larger, equal...). This would be the elegant way of explaining it :)

If you're an EE and interested in aerospace engineering, "avionics" is the keyword you are looking for. And no, there's no such disadvantage since nowadays a flying machine is almost nothing without proper electronics on it.

Nope; it's the conversation part that kills us the non-native speakers :) In fact, some people (like my teacher at the prep school) claim that non-native people pay more attention to the grammar making their writing better than some of the native speakers. Back on topic: @Confused: When you...

You're right. But it -depending on the numbers- takes more clock cycles than doing it with a LUT.

Neither mine (that's obvious I believe :) ). I'm not criticising his level of English as typing "please" instead of "please" wouldn't require any particular skill.

The voltage drop would be due only to electrical series resistance (ESR) of the capacitors. Other than that, in the situation you described, there is no reason for a voltage drop.

Electromagnets are highly non-linear in nature. You have to have a closed-loop control scheme incorporated with an actuator system having linear characteristic (like hydraulics maybe).

For the square part use a look-up table and an index to count up to x and read the table (which should contain the square of each x values). The rest is straightforward; addition.

It provides some hints if you try to find the upper and lower bounds on eigenvalues depending on matrix norm and matrix measure of A.

The thing is that the specific transistor model that you use in your circuit starts to open around 1V (as you correctly pointed out) but unlike what you claim it is supposed to enter the saturation region around 7V (not 2V). Check it here...

Umm, no offense, but have you ever tried to read your own post?

Yep :)

Hi, I see no particular challenge in the problem specified. Are you familiar with the root-locus concept? I guess you'd better first develop some primary insight on the subject through available resources. Do you have any access to the book "Modern Control Engineering" (Author: Ogata) or any...
